Imagine a five-pointed star. Now attach a word to each point and think of them as the core principles or values associated with how and why you create or make photographs. Today as we walk together on the Photowalk show, the philosophical YouTuber Sean Tucker discusses five that I have chosen, and we ask you to consider your own during this exercise of creative self-discovery.

It's also an expanded letters show today: the special nature of the pictures we make of strangers, collaborations, the wonderful opportunity when exhibiting your work, photographs on the side of a mountain and documenting where you live as a legacy.

Links to all guests and features will be on the showpage, my sincere thanks to MPB.com who sponsor this show and the Extra Milers without whom we wouldn't be walking each week.

WHY: A Sketchbook of Life is available here.
